如果不用 Rails 的话,哪些 gem 不能用?

u1450154824 — Thu, 08 Sep 2016 16:04:55 +0800

项目是 grape on rails，感觉 rails 有点浪费，想只用 grape 和 activerecord，但是发现用了其他的 gem，比如 carrierwave,doorkeeper，好像是比较依赖 rails.如果不用 rails，哪些 gem 是不能继续用的，或者怎么去配置才能继续用，有没有前辈有经验.@robbin，目前刚看了 robbin 前辈的 grape on rainbows 这个，很有启发. 这些是我用的 gems

如何一个 scope 中使用另一个 scope?

u1450154824 — Wed, 11 May 2016 09:51:03 +0800

比如我有

scope :type_one, -> { where(type:1) }
scope :type_two, -> { where(type:2) }
scope :type_all, -> { where(type:[1,2]) }

可以有这样的类似写法吗？

scope :type_all, :type_one,:type_two

carrierwave 使用 github 的版本不能搭配 aliyun 插件

@huacnlee 因为想做多图片上传，看到帖子说 carrierwave 原生支持，但是需要指定 github 主分支. 如下

gem 'carrierwave', github: 'carrierwaveuploader/carrierwave' 并且 model 里是 mount_uploaders :images, LocalUploader 不是 mount_uploader 如果，不用 github 的版本，会找不到mount_uploaders.

我试了一下，本地图片上传多图片可以成功. 但是如果使用了 gem 'carrierwave-aliyun' 会出现，

$ rails s

CarrierWave 如何从云存储下载文件。

u1450154824 — Fri, 22 Apr 2016 10:10:00 +0800

用的阿里云 oss 和 carrierwave-aliyun，上传现在是可以。我现在是在 model 里 mount_uploader。试过这样

uploader = BaseUploader.new
uploader.retrieve_from_store! 'd374181822cea77fd4957aa498c1d8e3.jpg'
uploader.cache_stored_file!

报错是

The specified key does not exist

希望有经验的前辈可以帮我解决一下。并且想知道 carrierwave 的正确使用姿势是什么样的？

刚开始用 sunspot ，导致原本的 post put 都会 400，为啥呢

u1450154824 — Fri, 15 Apr 2016 17:27:14 +0800

报错如下

Solr::Error::Http (RSolr::Error::Http - 400 Bad Request
Error: {'responseHeader'=>{'status'=>400,'QTime'=>1},'error'=>{'msg'=>'Exception writing document id Enterprise 45 to the index; possible analysis error.','code'=>400}}

Grape 的 params 如何剔除一个不需要的 param

u1450154824 — Wed, 13 Apr 2016 17:19:18 +0800

exactly_one_of 又应该怎么用

如果我希望有个特定的参数我想保护起来，不想外部传入，应该怎么做

比如 except_of 之类的？

Grape 怎么定义 JSON 的默认日期格式

u1450154824 — Wed, 13 Apr 2016 15:09:27 +0800

"created_at": "2016-04-13T06:01:15.000Z",
"updated_at": "2016-04-13T06:01:15.000Z",

比如我想要默认是

%Y-%m-%d %H:%M:%S'

应该在什么地方配置吗？
